they've mentioned about creating their own cryptocurrency and assured of 30% - 40% return monthly.
I don't know, but why even today, people tend to invest in this kind of scam. People are easily deceived and being scammed because they continue to do such thing as investing and having ROI monthly. There is no such thing as investing and having a guaranteed return without doing anything. Not only in crypto space, even in real world, people should realize it that earning money is not easy as that.
Scammers have the same concept, they keep on promising a sure return every month at a specific percentage, people should know this trick and even if they said they are government approved, you still have to do your own research. Theres a lot of crypto scam, dont get fooled easily and have your right knowledge always.
